INSULATOB.

Application tiled July 22, 1922.- Serial No. 576,756.

` The invention relates to insulators, and more particularly to the type used for attaching wires to buildings or other supports, and its object is to provide an inexpenslve form of insulator that may be readily attached. to the support and that will accommodate `line wires coming to or extending from it at different angles.

The invention further consists in the several features hereinafter set forth and I more particularl defined by claims at the conclusion hereo I In the drawings: Fig. 1 is an elevation l view of an insulator embodying the invention; Fig. 2 is a rear end view of the insulator; Fig. 3 is a vertical sectional view through the insulator; Fig. 4: is a vview similar to Fig. 3, showing a modified form of construction for anchoring the attaching `member of the insulator, andFig. .5 is a view similar to Fig. 3 showing `a modified form of the wire-receiving portion of the insulator.

1n each `instance the insulator includes abracket 6 preferably of porcelain and of square or polygonal shape so that it may be engaged by a wrench. -In Figs. 1 to 3, in-

g. 5, -a threaded attaching member 7 has its enlargedvpolygonal end A8 disposed in an opening 9 in the base portion ofthe block and securely fastened to `the block by a cement liller .10. In Fig.4

. the threaded attaching member 9 has bifuruniform diameter, such as a bolt, and concated portions 8 extending well into the body of the insulator in openings 11 ,and secured to the insulating block by a cement filler12. While the member 7 is shown as a lag screw it may be a threaded member. of

nected to a support by means of a nut, as will be readily understood. In Figures 1` to 4f, inclusive, the linereceiving part of the insulator consists of a member 13 having an eye or hook 13 having its shank 14 disposed within an opening 15 in the block and secured therein by a cement filler 16, the inner end of the. member 13 having an enlarged Yhead 17, preferably of polygonal formation to prevent turning. 1

ln Fig. 5 the line-receiving member is formed by a bolt 18 passing through a transverse opening 19 in the insulator block and carryin a bail 20. In any of the above forms t e insulator may be screwed into a wooden support, where the threaded memL ber is a lag screw, and in that way have its b ase firmly clamped to the support, but where the member 7 is a bolt the insulator may be screwed into' the nut of the bolt or into a threaded metal support to secure it in place, the square formation of the block permitting the operator to use avwrench in turning the insulator.

lin either instance the line wire may be passed through the eye of the member 13 or through the eye formed by the bail 20 metal parts may be secured in. position in such material during the rocess of molding, in which. case a cement fil er is'not necessary.

What I claim as my invention is:

1. An insulator comprising a .block of insulating material having polygonalA toolreceiving sides and having openln s at its ends extending into the interior of t e block, a threaded attaching member fixedly secured in one of said openings, and a relatively stiff wire-receiving member having a .part secured in the other of said openin s.

2. An insulator comprising a block of insulating material having openings extending into the block'at its ends, a threaded attaching member xedly secured in one of Said openings, and ajrelatively stilf looped wire-receiving vmember having apart secured lin the other opening, said lcoped` `as molded insulating material, so that the of the insulator, a-.threaded attaching member fixedly secured in said openin and a bail carried by the head end of t e block for receiving a Wire from different angles of approach with respect to said insulator block.

4. An insulator comprising a block of insulating material having polygonal Wrenchengaging sides and having openings at its ends extending into the interior of the block, a threaded attaching sc revv having a head non-rotatably secured Within one of said openings, whereby lthe insulator is mounted 10 on a support by the turning of a wrench engaging the polygonal sides, and a relatively Stif looped Wire-receiving member having a part secured in the other opening.

In testimony whereof, I aliX my signature.
